Description

Technical Field

[0001] The utility model relates to the technical field of wear testing, in particular to a sample leveling device. Background Art

[0002] During the friction and wear test, if the sample surface is not flat (the sample surface is not parallel to the base), the load will fluctuate, resulting in fluctuations in the friction coefficient and abnormal wear of the sample, which cannot reflect the true tribological properties. Therefore, the sample needs to be leveled before the wear test.

[0003] For example, the leveling device for rock direct shear friction experiment disclosed in the patent document with publication number CN106814030A includes a ball head and a ball seat. The ball head is located in a concave cavity on the top of the ball seat. The ball head can rotate in the concave cavity and drive the platform to move so that the friction surface of the rock sample to be tested on the platform is in a preset position. The leveling device adjusts the position of the platform by rotating the ball head until the rock sample to be tested on the platform forms surface-to-surface contact with the rock sample located above it, thereby achieving leveling of the sample.

[0004] Although the existing leveling device can achieve the leveling of the sample by rotating the ball head, the leveling requires continuous manual control of the rotation of the ball head and continuous observation of the angle of the sample, which requires high requirements for manual control and makes the leveling of the sample more difficult.

[0031] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0032] An embodiment of the utility model provides a sample leveling device, which is used to level the sample 10a to be tested for friction and wear before the friction and wear test of the sample 10a is carried out, so as to facilitate the friction and wear test of the sample 10a, and the leveling of the sample 10a can be achieved by pressing the sample 10a, thereby effectively reducing the difficulty of leveling the sample 10a, and solving the technical problem of high difficulty in leveling the sample 10a in the prior art.

[0033] like Figure 1-4As shown, a sample leveling device provided in this embodiment includes a base body 10, a flexible module 20 and a leveling template 30. The base body 10 is provided with a sample slot 11 and a leveling plane 12. The sample slot 11 is used to place the sample 10a to be leveled, and the leveling plane 12 is located on the peripheral side of the sample slot 11; the flexible module 20 is installed on the side of the sample slot 11 away from the leveling plane 12, and is used to support the sample 10a to be leveled, and can be deformed under the pressure of the sample 10a to be leveled; the leveling template 30 is provided with a pressing plane 31, and the leveling template 30 has a mold closing state and a mold opening state. When the leveling template 30 is in the mold closing state, the leveling template 30 is in contact with the leveling plane 12, and presses the sample 10a to be leveled through the pressing plane 31. When the leveling template 30 is in the mold opening state, the leveling template 30 is separated from the leveling plane 12.

[0034] Specifically, the sample leveling device is provided with a base body 10, a flexible module 20 and a leveling template 30. The base body 10 is provided with a sample slot 11 and a leveling plane 12. The leveling plane 12 is located on the peripheral side of the sample slot 11. The flexible module 20 is installed on the side of the sample slot 11 away from the leveling plane 12. Before the sample 10a is leveled, the sample 10a to be leveled is placed in the sample slot 11 and supported by the flexible module 20. The leveling template 30 is provided with a pressing plane 31. The leveling template 30 has a mold-locking shape. When leveling the sample 10a, the flat template cover is arranged on the base to form a mold closing state and fit with the leveling surface 12. At the same time, the pressing plane 31 of the closing template presses the sample 10a. During the pressing process, the sample 10a drives the flexible module 20 to deform, so that the top surface of the sample 10a fits with the pressing plane 31, thereby driving the top surface of the sample 10a to be in a horizontal state, realizing the leveling of the sample 10a, and effectively reducing the difficulty of leveling the sample 10a.

[0035] In this embodiment, after the leveling of the sample 10a is completed, the mold plate can be separated from the base body 10 to form a demoulding state, so that the top surface of the sample 10a is exposed, and the friction and wear test of the sample 10a can be performed through the leveled plane.

[0036] It can be understood that the base 10 can be any base 10 structure that can be fixed on the friction and wear test platform, such as a number of relatively arranged columns, support plates, etc. The sample groove 11 can be formed by enclosing various columns or support plates, and can realize any groove structure that can accommodate the sample 10a. The leveling plane 12 can be a horizontal support plane that can adjust the leveling template 30 to a horizontal state.

[0037] In some embodiments, Figure 1-4As shown, the base 10 includes a bottom plate 13 and an enclosure frame 14, the bottom plate 13 is fixedly connected to the test bench, the enclosure frame 14 is fixed to the bottom plate 13, the enclosure frame 14 and the bottom plate 13 enclose a sample slot 11, and the leveling plane 12 is located on the top surface of the enclosure frame 14. Specifically, the bottom plate 13 can realize the stability of the base 10 on the friction and wear test platform, the enclosure frame 14 can enclose the sample 10a, and form a leveling plane 12 enclosing the sample slot 11 on the top, and the leveling plane 12 cooperates with the leveling template 30 to ensure the leveling quality of the sample 10a.

[0038] In some embodiments, Figure 1-2 As shown, the bottom plate 13 is provided with a mounting hole 131, and the mounting hole 131 is provided for mounting screws. Specifically, the mounting hole 131 can facilitate the fixing of the bottom plate 13 on the friction and wear test platform.

[0039] It can be understood that the flexible module 20 can be any flexible material such as mud, plasticine, etc. that can be deformed under the pressure of the sample 10a, wherein the shape of the flexible module 20 can be adaptively set according to the bottom shape of the leveling sample 10a.

[0040] In some embodiments, Figure 3-4 As shown, the flexible module 20 includes a glue 21, and the glue 21 is bonded to the bottom wall of the sample groove 11. Specifically, the glue 21 has good flexibility and resilience, and a flat surface. When one side of the sample 10a squeezes the glue 21 under the pressure of the leveling template 30, the glue 21 will flow to the side of the sample 10a that is not pressed, and drive the side of the sample 10a to rise and contact the leveling template 30 under the rebound force, until the top surface of the sample 10a fits with the leveling template 30, so as to achieve the leveling of the sample 10a.

[0041] In this embodiment, since the shape of the sample 10a is in an uncertain state, before leveling the sample 10a, the top surface of the glue 21 can be molded into a shape that matches the bottom surface of the sample 10a, and then through the flexibility and rebound characteristics of the glue 21, the sample leveling device can adapt to the leveling of samples of various shapes.

[0042] In some embodiments, Figure 3 As shown, the mastic 21 is wedge-shaped, and the top surface of the mastic 21 is a support slope 211. Specifically, the support slope 211 can provide support for the sample 10a with a sloped bottom surface. When the sample 10a with a sloped bottom surface is leveled, after the bottom surface of the sample 10a is placed on the support slope 211, the top surface of the sample 10a is in a nearly horizontal state, and then the top surface of the sample 10a can be adjusted to be completely horizontal by pressing the pressing plane 31, thereby facilitating the leveling of the sample 10a with a sloped bottom surface and improving the leveling quality of the sample 10a.

[0043] In some embodiments, Figure 4 As shown, the glue 21 is square, and the top surface of the glue 21 is an arc-shaped support surface 212. Specifically, the support slope 211 can provide support for the sample 10a with an arc-shaped bottom surface. When the sample 10a with an arc-shaped bottom surface is leveled, after the bottom surface of the sample 10a is placed on the arc-shaped support surface 212, the top surface of the sample 10a is in a nearly horizontal state, and then the top surface of the sample 10a can be adjusted to be completely horizontal by pressing the pressing plane 31, thereby facilitating the leveling of the sample 10a with an arc-shaped bottom surface and improving the leveling quality of the sample 10a.

[0044] In some embodiments, the top surface of the glue 21 can also be shaped into any shape such as a continuously curved surface, a conical surface, etc. that matches the bottom surface of the sample 10a, thereby achieving leveling of samples of various shapes.

[0045] It can be understood that the leveled sample 10a can be fixed by friction with the base 10 or other locking structures.

[0046] In some embodiments, Figure 2-4 As shown, the leveling template 30 and the base body 10 in the mold-closed state enclose a glue-pouring cavity 40, and the glue-pouring cavity 40 is used for pouring resin. Specifically, through the setting of the glue-pouring cavity 40, after completing the leveling work of the top surface of the sample 10a, the resin can be poured into the glue-pouring cavity 40, and the sample 10a can be fixed by curing the resin, and then the leveling template 30 is separated from the base, and the friction and wear test can be carried out with the sample 10a fixed by the resin.

[0047] In some embodiments, the inner wall of the glue pouring cavity 40 is coated with an oil layer (not shown in the figure). Specifically, the oil layer can prevent the resin from bonding with the inner wall of the glue pouring cavity 40, and facilitate the demoulding of the resin.

[0048] In some embodiments, Figure 1-4 As shown, the leveling template 30 is provided with a glue injection hole 32, and the glue injection hole 32 is communicated with the glue injection cavity 40. Specifically, the glue injection hole 32 can facilitate the injection of resin into the glue injection cavity 40.

[0049] In some embodiments, Figure 3-4 As shown, the base body 10 is provided with a demoulding hole 15, which is connected to the glue injection cavity 40 for resin demoulding. Specifically, after the friction and wear test of the sample 10a is completed, the leveling device is first disassembled from the experimental platform and the leveling device is inverted, and then the solidified resin is knocked through the demoulding hole 15, so that the solidified resin can be separated from the base, and the resin and the sample 10a can be demoulded.

[0050] In this embodiment, Figure 3-4As shown, the demoulding hole 15 is arranged on the bottom plate 13, and the experimental platform is provided with a blocking protrusion. After the bottom plate 13 is installed on the experimental platform, the blocking protrusion is inserted into the demoulding hole 15 to block the demoulding hole 15, thereby preventing the resin from leaking out of the demoulding hole 15 when pouring the resin.

[0051] The specific working principle of the sample leveling device provided by the embodiment of the utility model is as follows: when performing the leveling work of the sample 10a, the leveling device is fixed to the friction test platform through the bottom plate 13, and the sample 10a to be subjected to the friction test is placed in the sample slot 11. After adjusting the angle of the sample 10a, the leveling template 30 is fitted with the leveling plane 12, and the pressing plane 31 presses the sample 10a, so that the leveling of the sample 10a can be achieved. After completing the leveling of the top surface of the sample 10a, resin is poured through the glue pouring hole 32 to fix the leveled sample 10a, and then the leveling template 30 is separated, and the friction and wear test can be carried out through the top surface of the sample 10a. After completing the friction and wear test of the sample 10a, the resin is knocked through the demoulding hole 15 to demould the resin and the sample 10a, and then the leveling of the next sample is carried out.

[0052] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
